Abstract: Objective: To determine the threshhold of multiple auditory steady-state responses (ASSR) and pure tone audiometry in children aged five to ten with normal hearing, and to explore the correlation between them. Methods: Thirty children with normal hearing had the ASSR and pure tone audiometry determined at 0.25, 0.5, 1, 2, 4 and 8 kHz. The coherence and correlation between the two groups were determined by the t test and the correlated modulus t test. Results: The different average threshholds of ASSR and pure tone audiometry at all tested frequencies ranged from 11 to 16.50 dBHL. There was a statistical difference between the result obtained by ASSR and pure tone audiometry at all tested frequencies (P＜0.05), especially at 0.25kHz and 0.5kHz (P＜0.01).　The correlation was significant between the results by ASSR and pure tone audiometry at all tested frequencies (P＜0.05) by using the correlated modulus t test,Conclusion: In the middle or high frequencies, there are good correlations between ASSR and pure tone audiometry. However, there is a numerical value between them. It is feasible to confer the pure tone hearing threshhold of children aged from five to ten by determining the threshhold of ASSR and by using the numerical value.
